METHOD FOR DETERMINING A MECHANICAL PROPERTY OF AN AGRICULTURAL SOIL

The invention relates to a method for determining a mechanical property of a soil over which rolls a tyre mounted on a vehicle, said tyre being provided with a sensor configured to acquire a measurement signal representative of the evolution of the curvature of the tyre as it rolls over the soil, co...

Beschreibung
Zusammenfassung:	The invention relates to a method for determining a mechanical property of a soil over which rolls a tyre mounted on a vehicle, said tyre being provided with a sensor configured to acquire a measurement signal representative of the evolution of the curvature of the tyre as it rolls over the soil, comprising the following steps: - acquiring, by means of the sensor, a measurement signal representative of the evolution of the curvature of the tyre as it rolls, - determining, on the basis of the measurement signal, measurement data comprising: a) a first parameter (KSin) representative of a run-flat speed of the tyre when in contact with the soil, and b) a second parameter (KSout) representative of a rounding speed of the tyre when in contact with the soil, and - determining the mechanical property of the soil as a function of the first parameter (KSin) and/or of the second parameter (KSout).
